Murphy 100-500F Direct Mounting Temperature Swichgage with 1/2 NPT Thermowell - SDB501-2
The Murphy SDB501-2 is a Direct Mounting Temperature Swichgage device that provides an accurate direct-reading gauge with an adjustable limit switch to activate alarms and/or shutdown. A knob on the front of the Swichgage allows you to adjust the limit switch trip point. Pointer movement is actuated by a bi-metallic sensing element. When the indicating pointer on the SDB501-2 touches the adjustable contact, a one-wire-to-ground circuit is completed to shut down the equipment and/or actuate audible or visual alarms. Proper relays or Tattletale annunciators (magnetic switches) must be incorporated into the system. A thermowell (separable socket) is used to facilitate maintenance of a temperature Swichgage and to protect the temperature sensing bulb from extreme amounts of system pressure. Applications: The most common use of the SDB Series is to monitor gas compressor temperatures. Engine exhaust temperature can also be monitored to indicate over-loading or lean fuel mixtures; or use the SDB to help coordinate loads on twin-engine installations. FEATURES:Easy to Read DialBi-Metallic Sensor100 to 500°F (40 to 260°C)Dials Scaled in Degrees Fahrenheit/CelsiusDie-Cast Aluminum1/2 NPT Thermowell PRODUCT SPECIFICATIONS:Part No.: SDB501-2Temperature Ranges: 100 to 500°F (40 to 260°C)Sensing Bulb Material and Size: 304 stainless steel; 1/2 in. dia. x 4 in.
